Along the way, you’ll uncover memories to help you in your quest. You’ll encounter tricky puzzles that stand in your way of progressing to the next level. As you progress to Chapter 2, you’ll face the missing plate puzzle in the basement boiler room. Solving it is possible once you gather all the missing pieces. So, let’s see in this guide how to solve Alone in the Dark Boiler Room Puzzle.
How to Solve Alone in the Dark Boiler Room Puzzle?
To solve the Alone in the Dark Boiler Room Puzzle, you’ll have to find the two missing plates of the puzzle. The first one is located beyond the boiler itself and the other one is located in one of the patient’s, Cassandra’s room. To get the two pieces, make sure you’ve finished the Astronomical Clock puzzle and come back from the Hateful Mound. Once you’re back, you can start working on fixing the Boiler.
Here’s how to find the two missing pieces of the Boiler:
The First Missing Piece in the Boiler Room
The first missing plates can be found in the corner of the Boiler room, just past the steam leak. Before you can reach it, you’ll need to fix the leak. To get to the missing plate, first, you need to switch off the circuit of the broken boiler.
You can find the valve handle in the Cellar, behind a locked gate. The key to unlocking the gate can be found in the Drawing Room on the first floor. Use the Palette Knife to access the key. Once you have the key, head down to the Cellar and enter the locked area.
In the cellar, there’s the Valve Handle from the Boiler in the back left corner. But it’s blocked by a puddle of water near a live wire, so, you’ll need to cut the power in the basement first.
To cut the power in the basement, look for the Switch on a wine rack to the right. Grab it, connect it to the Circuit Box nearby, and then you can safely turn off the power and grab the Valve Handle from the boiler in the back.
After you grab the Valve Handle, head back to the Boiler room. Be cautious, there’s an enemy lurking in the basement hallway.
Connect the valve handle to the Boiler and turn it to stop the leak. Once fixed, you can access the area beyond the Boiler. The first missing piece of the Boiler plate can be found in the back corner once Jeremy’s body disappears.
The Second Missing Piece in Cassandra’s Room
The second missing piece can be found in a drawer in Cassandra’s Room on the second floor, right next to the Sitting Room. You’ll receive the key to the Sitting Room and the Palette Knife when you come back to Derceto from the oil rig. Once you enter Cassandra’s Room, you’ll find a drawer with a padlock in this room, similar to the one in Perosi’s Room.
But to unlock it, you gotta first figure out a puzzle with medicine bottles in the room. And guess what? You need to find two missing medicine bottles before you can even start solving the puzzles. The first medicine bottle, Margrave Liniment bottle is located on the desk in the middle of Cassandra’s Room.
To get the second medicine bottle, Dr. Jenkins Lozenges, head to the second floor. Take the Servant’s Stairs. Once you’re up there, find the hallway next to the Mezzanine and make your way to the staircase on the north side. Go down to the Grand Parlor where you’ll see a piano in the center of the room. Grab the key sitting on top of the piano – that’s the key to the Medicine Box.
Grab the key and make your way to Lottie’s Room to pick up the second bottle of medicine. Open the medical box with the key and you’ll find the second medicine bottle, Dr. Jenkins Lozenges.
Once you have both the medicine bottles, go back to Cassandra’s Room and solve the medicine bottle puzzle. To complete the row of medicine bottles, simply rotate and place them to form a continuous line.
This will reveal the numbers 2, 5, and 7, which correspond to the astrological signs Pisces, Gemini, and Leo. Enter this combination in the lock of the drawer and you’ll find the second missing piece of the boiler plate.
Rearrange the Missing Pieces
Once you’ve got both missing pieces of the boiler plate place them into the puzzle and solve it. You’ll have to swap and rotate pieces to put together a picture as indicated in the image below of a farm and chapel. You can even refer to it in the Commonplace Book. Once that’s sorted, the boiler will fire up again, revealing three numbers on the pressure gauges: 9, 7, 5.
Type them into the Talisman on the boiler in order to reveal images of the Cellar. From there, just head back to the Cellar from the Boiler Room to explore the new area you can now check out.
And that concludes our epic journey through solving the Alone in the Dark Boiler Room Puzzle. Keep an eye out for more thrilling game guides filled with the latest game updates.
